All conglomeraties such as inspection, food hygiene, environment measuring.Compared with the conventional sedimentation method, centrifuging, post embrane method, paramagnetic particle method has
The features such as extraction efficiency is high, separating rate is fast, equipment needed thereby is few.
Magnetic frame is the conventional magnetic separating device of laboratory, as a kind of externally-applied magnetic field in magnetic separation technique, can be inhaled
The nanometer magnetic bead of attached various magnitudes, realizes that magnetic bead is separated with sample solution.The separating step of sample approximately as：Magnetic will be contained
The sample solution of pearl is placed in centrifuge tube, after the modes such as agitated, ultrasonic, concussion are disperseed, centrifuge tube is placed on magnetic frame
Hole position in, external magnetic field effect is applied by Magnet set on magnetic frame to solution, the magnetic bead in sample solution will
It is collected near the side of Magnet, after no scattered magnetic bead in solution, only solution need to be removed or go to complete magnetic
Pearl and the sharp separation of sample solution.
Although magnetic frame on the market can meet the requirement of portions of client, but still come with some shortcomings, such as：
(1) most of magnetic frame is often unitary design, that is, be in the middle of common centrifuge tube shelf or lower end is fixed and set
There is one piece of magnetic piece, and need to carry out magnetic bead the steps such as multiple cleaning and eluting in " paramagnetic particle method " extraction process, therefore needs are right
Magnetic bead separation repeatedly and dispersion, using the magnetic frame of this class then need after separation is complete centrifuge tube be transferred to it is common from
After adding cleanout fluid or eluent to be disperseed in heart pipe support, then centrifuge tube is moved on to separated on magnetic frame, during need
Centrifuge tube is shifted repeatedly, it is cumbersome, extend extraction time.
(2) the centrifuge tube specification that magnetic frame is suitable for is single, it is impossible to while can meet the centrifuge tube to different size carries out magnetic
Property separate.In sample separation process, existing magnetic frame can only be suitable for a kind of specification centrifuge tube simultaneously, to different capabilities
Sample, especially to sample it is little carry, in carry, carry greatly during need select different size magnetic frame, increased user's
Cost.
(3) do not rocking easy to fall off with centrifuge tube in switching process, using uneasiness from the anti-skidding bayonet socket of adaptation centrifuge tube
Entirely.

Preferably, described efficient magnetic frame, wherein, with the built-in groove as axle, second hole position and the 3rd hole
Position is respectively positioned at the both sides of the built-in groove.
Preferably, described efficient magnetic frame, wherein, the internal diameter and the first hole position of second hole position and the 3rd hole position
Internal diameter it is different.
Preferably, described efficient magnetic frame, wherein, the internal diameter of first hole position is 10mm.
Preferably, described efficient magnetic frame, wherein, the internal diameter of second hole position is 16mm.
Preferably, described efficient magnetic frame, wherein, the internal diameter of the 3rd hole position is 28mm.
The beneficial effects of the utility model are：This utility model provides a kind of multifunctional magnetic-force frame, and structure is novel, by 3
The centrifugation pore for planting laboratory regular size is fully combined together, and device volume is little, easy to carry, is suitable for various centrifuge tubes
Specification, at the same complete sample it is little carry, in carry, carry greatly；Additionally, the magnetic frame one-hand operation, arbitrarily plus-minus Magnet quantity, grasps
Make simple, good separating effect saves experimental period, substantially increases work efficiency.
Description of the drawings
Fig. 1 is the structural representation of efficient magnetic frame.
Left views of the Fig. 2 for Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
Fig. 1 and Fig. 2 is referred to, the efficient magnetic frame of its explanation one embodiment of this case, which includes：
Support body 1, which includes a built-in groove 2 and the first hole position 3 positioned at 2 both sides of built-in groove；
Magnetic piece frame 4, which is in the way of slidable movement into and out built-in groove 2；Several appearances are provided with magnetic piece frame 4
Put the separation 5 of magnetic piece；Can neatly be selected filling out for magnetic piece to put position and quantity, reach precise control magnetic as needed with this
The purpose of power regional extent.
Wherein, the notch 6 of built-in groove 2 is arranged on the side of support body, and the opposite side relative with the notch 6 is additionally provided with second
Hole position 7 and the 3rd hole position 8；
Elastic buckle 9 is equipped with first hole position 3, the second hole position 7 and the 3rd hole position 8, centrifuge tube is stablized with improving
Property.
Wherein, with built-in groove 2 as axle, the second hole position 7 and the 3rd hole position 8 both sides respectively positioned at built-in groove 2 are (such as Fig. 2 institutes
Show).
Wherein, the internal diameter of the second hole position 7 and the 3rd hole position 8 is different from the internal diameter of the first hole position 3；To meet making for many specifications
Use demand.
Wherein, the internal diameter of the first hole position 3 is preferably 10mm.
Wherein, the internal diameter of the second hole position 7 is preferably 16mm.
Wherein, the internal diameter of the 3rd hole position 8 is preferably 28mm.
The working method of this case magnetic frame：
1) dispersing mode：First the magnetic piece frame 4 for being filled with magnetic piece is detached from support body 1, by magnetic bead and sample solution point
